The Trella™ MIPS® offers a comfortable fit, with deep coverage and open ventilation in a design that is suitable for nearly any ride. It’s built using In-Mold construction to reduce weight while enhancing durability that stands up to everyday use. The ease and comfort of our acclaimed Roc Loc® Sport MIPS fit system makes fitting as easy as turning a dial, and the fit system is seamlessly integrated with the Multi-Directional Impact Protection System (MIPS), which can redirect energy and provide more protection in certain impacts. When you put it all together, you get the versatility you need to ride everything from forested fire-roads to swooping singletrack trails to the city streets.

All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro’s MIPS-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider’s brain in certain impacts.
